This volume offers a contemporary review, methodologically and theoretically, of some basic issues in early human brain-behaviour development. It presents updated reviews of the "state of the art" in research on a number of core issues in developmental biopsychology, written by distinguished scientists. The focus is on the biological basis of early functional development in the human, in particular with respect to: state organization, motor control, perception of sound and speech, visual attention and social interaction. Attention is paid to normal development as well as to deviance and early risk factors. The volume is designed to serve as a key reference for researchers and interested scientists in developmental neuropsychology and developmental biopsychology, neuropaediatrics and biology, and related fields.
